Influência do arranjo espacial na cultivar de soja Bônus

Abstract

The sustainability of a system depends on the rational use of its resources, being no different in a cultivation system. The present study aimed to evaluate the influence of different densities and row-width on a soybean cultivar BMX Bonus Ipro. For this examined plant height, quantity of nodes, quantity of branches, diameter of stem, amount of pods with one, two and three seeds per plant, total amount of pods per plant,1000 grain mass and yield. The design was completely randomized (DIC), being composed of three treatments and four replicates. In treatment 1 was evaluated 50cm between planting row and 13.1 plants per meter in the planting line, in treatment 2 used 50cm between planting rows and 7.9 plants per meter, already in the third 25cm between rows and 9.1 plants per meter. The treatment 3 showed bigger height of plants and weight of 1000 grains; but this it presented lesser amount of pods with one, two and three seeds. This treatment presented also lesser amount total of pods. The diameter of the stem and number of nodes no show significant difference.
